Abdominal aortic aneurysm detected by a consumption coagulopathy

: Consumption coagulopathy with clinical symptoms reveals aortic arterial aneurysm in less than 5%. Aneurysmal repair with graft is able to remove hemostasis abnormalities for a long time. The physiopathology of these abnormalities is described here through the study of an operated case. It is questionable to use heparinotherapy as exclusive treatment for non operated patients. Heparinotherapy during perioperative period is also a matter of debate. Surgical implications of the consumption coagulopathy are listed: preoperative plasma and platelets transfusions, fibrinogen and antithrombin III perfusions, meticulous hemostasis, minor dissection, use of a women graft. Coagulation disorders disappear before the first postoperative week. Persistent or recurrent consumption coagulopathy invite us to look for a pathological association which often turns out to be a neoplasm.
